- To @ZZ whom t mag/concern.-

Be it known that 1 JEREMIAH CAMPBELL, a

citizen ofthe United States, residing at Chelsea, in the county'pofSunolk and State of Massachusetts, haveinvented a new and usefulImprovement inHoisting and Conveying Apparatus, of which the followingis a full, clear, and exact description, reference beingv had ,to theaccompanying drawings, forming apart of this specification, inexplainingits nature.

The invention comprises a movable hoisting and conveying apparatusLemploying a steam-shovel, its operating devices, a transferring-trolley,and an operating-engine movabley horizontallyand having a short boom-.section upon which lthe v.trolley is movable and which is used inconnection with a series of stationary booms with which thesaid .mevableboom-section is brought into line and used in any order or sequencedesired;

In' the drawings,Fignre 1 is a view largely in side* elevation of myimproved apparatus. l

Fig. 2 is aview insetion upon the dotted line 2 2 of Fig. 'land inplanliof parts below said linegl Fig. 3 is a view principally in plan,

showing'a number of stationary booms and' the movable boom-section,steam-shoveh'trolley-operating engine, &c.

A represents a car or truck, the wheels a ofk which are mounted upon thetracks a', by

- -which the car, or .trucktmay be moved in any desired direction or toany required location. This car or trucksupports at one side a shoveland trolley-operaiting'en gine B. A t the other -side it supports ahopper C, having an opening c in its bottom. The car or truck alsosupports above the engine B asection D of a trolley-boom which isadapted-to be used in connection with any one of any desired number oflstationary booms B', the inner ends of which are arranged to be inoperative rela'- tion to the movable boom-section vD,vwhenr brought inline therewith. The movable boom-section D isemployed. principally as ap rest or support for the trolley E when itis 4bein g moved from oneboom to another. vThe trolley is showni'n full lines upon the stationso'n The trolley is movable bac ward and forary boom B' in Fig. 1 and indotted lines-upon the movable boom-section D.

ward` upon any one of *thestt-.ionary boms B b vfan voperating-ropewhichpasses from fone end of the trolley', about a sheave b at the lend ofthestationaryY boom, backward over the stationary `boom and the movableboomsection, about afsheave 19'., to aWinding-spool D of theengine,about which it `is-wonnd and from which it extends backward overasheave, companion to the Vsheave b', vto the trolley E. The trolleycarries a set e of two sheaves, over whichl the shovel operating ropesextend to the shovel `F. The shovel is a steam'- shovel of theclam-shell-variety, which automatically takes its load and releases .it'and is operated by a hoisting and lowering rope f and an opening andclosing rope j".v `These ropes pass "over the set of trolley-sheaves cto sheaves b attherear end of the movable boom-section D and fromVthenceae-their'respective'winding-druins.

.The position of the steam-shovel and its operating-ropeswhen inloperative position vupon a fixed boom is represented in full lines inFig. 1.

upon the,movableboom-section B' to a position represented by dottedlines in Fig. 1. It is therefore desirable to supply each stationaryboom-section with a trolley-actuatin g rope ywhich shall b e rovethrough the sheave b, at

the end thereof,and which shall have its ends` arranged near the rearend of the boom. Any desirable shovel and trolley and operatingenginemay be employed. y The obect of the invention is to provide `means foremploying the same .automatic hoisting and con-veyingshovel and itsAoperating devices -upon any; one'.` of a= series of booms whereby thecoal'or material beneath said booms may be hoisted and conveyed ortransferred.

It will be neces-v .'sary, however, to disconnect the trolley'from itsoperating-ropes and to move'the trolley` IOO While I have shown theshovel as hoisted and lowered and opened :md closed ,by two ropes, 'Iwould say that the number of ropes so employed for accomplishing thispurposey forms no part of my present invention, and I should consider itpracticed if the shovel were hoisted and lowered and opened and closed?by a single rope or by more than two ropes.

Having'thus fully described my invention, l I claim and desire to secureby Letters Patent of the UnitedStates- 1. In a hoisting and convey-ingapparatugg the combination of a movable car or truck, a shovel andtrolley operating engine mounted thereon, a space' in which thesteam-shovel may be held while it is beingI moved withthe car ort-ruck,and a movable boom #section adapted to hold the trolleywhile it isbeingk l transferred with the shovelland engine, .and

two or more stationary bepm-sections with which said movable section isadapted to co,

j operate.

2. In combination, the car or truck A, .a shovel and trolley operating`engine carried 1. thereby, a hopper C, a movableboom-'section D adaptedto lreceive and hold the trolley, the

sheaves mounted thereon and two' 'o1' more stationary booms.

.3'. The combination of the truck or car A, the shovel and trolleyoperating engine thereon, the steam-shovel carried thereby with itsoperating-ropes connected therewith,the trolley "eer-Pied-therebydiscomiected from its operating-rope and a boom-section orsupport for said trolley carrying'sheaves for the operating-rope andwhich `boom-section or support is adapted to be moved into line with astationary boomesection, and said stationary boom-section.

4. 'The combination ina. hoisting and conveying apparatus, of a movabletruck or car, a. trolley-support :mounted therein, :a trolley carriedthereby, fa.' support at one side of and below the trolley-support, a`steam -shovel .adapted to be .carried upon vsaid support and the shoveloperating rope extending vover a.

sheaivefcm said trolley to an operating-engine.
